Higher yields / Safe & Reliable / Smart / User-friendly
The series products adopt 2 MPP trackers design. Equipped with screw crimp terminal for DC and AC side, convenient installation and maintenance. With high detection accuracy, when the load power is less than 2%, the measurement accuracy is still high. In addition, it allows the system to be monitored and controlled remotely.
Smart Monitoring Platform
Thanks to the smart monitoring platform, Deye full series inverter products support remotely shutdown immediately when accident occurs. Setting parameters and FW update remotely, which makes PV plant O&M easier.
